I plan on leaving everything from the diverters back completely stock, so I believe the 2.5" diverters are what I need, but I'm not sure.

Anyway, are there any vendors who sell all of these items? Or am I just going to have to order everything seperately from different vendors?

Thanks for any and all help!

We're a Warehouse Distributor for Magnaflow right here in San Antonio with you and have several different Magnaflow systems in stock if indeed you'd consider a Magnaflow system. We obviously wouldn't have to ship it to you (will call pick-ups available) so you'd save around $50 right there. Feel free to PM us if we can help.
